, this is what you have - fishable flies that will catch fish, but aren't very well tied. The first thing I would do is get some Sally Hansen's Hard as Nails nail polish, and a pin or needle and put an extra coat of 'head cement' on the wraps at the eye to aid durability.
I expect some of the flies are large for the bug they are imitating and you may find that some will work better for sunfish than for trout because of that.
The big one is an attractor and almost looks like a salmon fly that has lost its hackle at the front. Use it for bass.
Top row: a generic mayfly nymph - get rid of that thread at the head before cementing again.
Prince Nymph - a good all-round nymph/attractor - get rid of that thread at the head.
Black generic mayfly nymph
Poorly tied American style Pheasant tail nymph - or maybe a crane fly adult - the long legs are rather confusing.
Black stonefly nymph - good anytime in the water just downstream from a riffle in cold, clear water - esp. good in the spring.
A generic wet fly - imitating either a nymph emerging or an adult drowning. By the size I think it would be better in the spring or for sunfish - kind of large for a mayfly.
Second row: a brown stonefly nymph - see above
I think this is a chironomid (midge) imitation - but kind of large. It might actually work best if the tuft we see was greased with floatant and fished in the surface film.
a large generic mayfly nymph - probably worked best when there is a hatch of green or brown drakes (large mayflies) which I think are prevalent in some rivers in July
a brown stonefly nymph
A cased caddis worm imitation (or mayfly), looks like a nice small size, can be fished all season
a wet fly similar to a Hendrickson nymph - best fished early in the year, but it also might be a little large.
If you are starting to fish this fall, I suggest you should get some woolly buggers in black, purple, pink and blue. Nymphs are good for steelhead, but WBs are a little more reliable. And don't by any more flies at Canadian Tire, they are designed to catch fishermen, not fish.
